Fascinating subject that uses a variety of manual techniques to address the physical concerns of the body. The main difference (in this course anyway) is the use of nerve pathways and the unlocking of such from different muscles that are causing the dysfunction. massage is applied in a slow controlled manner that goes very deep into the nerve but not so hard as to irritate more. Once the nerve is released- the pain decreases or is completely removed.
I found a video that shows a small bit.
